Kupambana mu Chiwonetsero cha Micro LED: Pixel Yaing'ono Kwambiri Padziko Lonse ya LED pa 90nm yokha

Pachitukuko chachikulu chaukadaulo wowonetsera, ofufuza ochokera ku Yunivesite ya Zhejiang avumbulutsa pixel yaying'ono kwambiri padziko lonse lapansi ya LED - yoyezera basi.90 nanometers (nm)- kuyika benchmark yatsopano pakuwongolera ndi kuchita bwino pazowonetsa zam'badwo wotsatira.

Motsogozedwa ndi Pulofesa David Di ndi Pulofesa Baodan Zhao, gulu lofufuza lidasindikiza zomwe apeza muChilengedwepansi pa mutu"Kutsitsa ma LED ang'onoang'ono ndi nano-perovskite."Ntchito yawo imabweretsa gulu lapamwamba kwambiri la LED lomwe limatha kukwaniritsa127,000 mapikiselo pa inchi (PPI)- Chisankho chapamwamba kwambiri chomwe chinajambulidwa muukadaulo wowonetsera wa LED.

Chifukwa Chake Kuphulikaku Kuli Kofunika?

Mawonekedwe a Traditional III-V semiconductor-based Micro LED akukumana ndi zofooka zazikulu:

• Mtengo wapamwamba wopanga

• Kutsika kogwira bwino kwambiri kukakhala pansi pa ~ 10 microns

Yankho latsopano? Ma Perovskite LEDs (PeLEDs), omwe amapereka maubwino angapo:

• Kuchepetsa ndalama zopangira

• Kuchita bwino kwambiri pamiyeso ya nanoscale

• Kuchuluka kwa kuchuluka kwakunja (EQE) kwa 20-30%, kufananiza ndi ma OLED

• Nthawi yayitali yogwirira ntchito ikuyandikira miyezo ya OLED

Zatsopanozi zimatsegula chitseko cha zowonetsera zapamwamba, zotsika mtengo zomwe poyamba sizinkatheka ndi luso lamakono la Micro LED.

The Innovation Behind the Record-Breaking Pixel

Pamtima pa izi ndi njira yopeka yodziwika bwino yotchedwandondomeko yokhudzana ndi malo. Njirayi imagwiritsa ntchito wosanjikiza wotsekera wokhala ndi mazenera opangidwa kuti ateteze kuwonetseredwa kwachindunji kwa zida za perovskite ku maelekitirodi, kuchepetsa kwambiri kutayika kwamphamvu kosatulutsa mphamvu.

Zotsatira zake, ma PeLED amasunga bwino kwambiri ngakhale pamiyeso yaying'ono kwambiri - chinthu chofunikira kwambiri pakugwiritsa ntchito mtsogolo mwanzeru.

Kufananiza kwa Magwiridwe: PeLED vs Traditional Micro LED

Ma PeLED amatsogola bwino ma LED amtundu wa Micro LED mu scalability komanso kuchita bwino pamasikelo ang'onoang'ono, kuwapangitsa kukhala oyenera paukadaulo wowonera wamtsogolo.

Chiwonetsero cha Prototype Active-Matrix Micro PeLED

Gululi lidawonetsanso chiwonetsero chogwira ntchito cha chiwonetsero cha Micro-PeLED chogwira ntchito pogwiritsa ntchito ndege zowonda zamtundu wa TFT (TFT) - kutsimikizira kuthekera kwake pakugwiritsa ntchito, kutsimikizika kwakukulu.

Zomwe zingagwiritsidwe ntchito ndi:

• Augmented Reality (AR) ndi Virtual Reality (VR)- Kumveka bwino kwa retina ndi PPI yokwezeka kwambiri

• Zowonetsa Zovala- Wopepuka komanso wogwiritsa ntchito mphamvu

• Magalasi Anzeru & Zowonetsera Zamutu (HUDs)- Kuwala kwakukulu ndi kugwiritsa ntchito mphamvu zochepa

Zovuta ndi Njira Yotsogola

Ngakhale izi zikuyenda bwino, zovuta zingapo zatsala ma PeLED asanafikire kupanga zambiri:

1. Moyo wonse ndi Kukhazikika: Ngakhale kuti ma PeLED amakono akuyandikira moyo wa OLED ngati moyo, kukonzanso kwina kumafunika kuti pakhale malonda.

2. Scalability: Kusintha kuchokera ku ma prototypes a lab-scale kupita kukupanga ma voliyumu akulu kudzafuna zaluso monga kusindikiza kwa inkjet ndi kukonza-to-roll.

3. Mpikisano: Ukadaulo wa Micro OLED komanso matekinoloje a Micro LED opangidwa ndi madontho akuchulukiranso akupita patsogolo mwachangu.

Komabe, kachulukidwe ka pixel kamene sikanachitikepo ka ma PeLED amawapatsa mwayi wapadera mumisika yamisika yokhazikika.

Mawonekedwe a Makampani: Kukula mu Thin-Film Micro LED

Motsogozedwa ndi kufunikira kwa zowonetsera zowoneka bwino kwambiri komanso kupita patsogolo kwaukadaulo wa haibridi wa LED, msika wapadziko lonse lapansi wamakanema a Micro LED wakonzeka kukula kwambiri. Magawo akuluakulu omwe akulimbikitsa kukula uku ndi awa:

• Mahedifoni a AR/VR

• Ma HUD amagalimoto

• Zovala zanzeru

Malinga ndi kusanthula kwaposachedwa kwamakampani, izi zithandizira kusungitsa ndalama ndi R&D mu perovskite ndi matekinoloje ofananirako.

Kutsiliza: Nyengo Yatsopano Yowonetsera Ma LED a Micro

Kukula kwa a90nm PeLED pixelzikuwonetsa kusintha kwaukadaulo waukadaulo wowonetsera. Ndi:

• Kachulukidwe ka pixel kosaneneka (127,000 PPI)

• Mitengo yotsika yopangira poyerekeza ndi ma III-V Micro LEDs

• Kugwira ntchito mokhazikika pamiyeso ya nanoscale

Zowonetsera za Micro LED zochokera ku Perovskite zili bwino kuti zitsogolere zatsopano zatsopano - makamaka mu AR / VR, zipangizo zovala, ndi mapulogalamu ena apamwamba.

Pamene kafukufuku akupitilira komanso njira zopangira zikukula, ma PeLED posakhalitsa atha kukhala muyezo wazowonetsa kwambiri m'mafakitale.
